An object on a frictionless surface is attached to a spring having a spring constant of 235N/m. 50.0J of work was done on the spring to stretch it to its maximum amplitude. As the mass passed through its equilibrium position, a motion detector determined that its speed was 14.6m/s.
What was the position of the object when its speed was 5.00m/s?3 AnswersPhysics8 months ago

I've been trying to do this for hours and just can't figure it out.
We graphed our experimental data on sheets, then used the equation to compare to a theoretical equation. I'm supposed to make an equation relating the constants but I honestly just have no idea do it. The teacher did one of them for me but I just simply can't figure it out. Please help me out guys.

The lab questions (particularly C and D): https://gyazo.com/d82678c3e6e71699229f73f33952f630
Keep in mind Part 1 was done for us, I just need help figuring out 2 and 3. I got some equations down but I'm just not sure if they're right. I really don't know what I'm doing and spent the past few hours trying to do it. Please help!!Mathematics11 months ago
A red car goes through a stop light at a speed of 60.0 km/h. A police car (at
rest) starts chasing the car with an acceleration of 4.5 m/s
. How far away
from the intersection does the police car catch the red car if:
a. the police car leaves the intersection at the same time
b. the police car leaves the intersection 3.0 s later
Can someone explain this to me with steps? Thanks!1 AnswerPhysics11 months ago
I know the equation that's supposed to be used, Vf=Vi+at but I'm not sure what to do with the change in time, if I just write time as 13s we're neglecting the first 3 seconds of constant velocity. If I add it beside the initial velocity I'm changing the equation, is that okay? What should I do?
Here's the question:
A particle is moving with an initial velocity of + 112 m/s at t = 0 s. The particle has no acceleration
until t = 3.0 s, after which it has an acceleration of - 4.0 m/s2
. What is the velocity at t = 16.0 s?3 AnswersPhysics11 months ago
I'm in Grade 11 right now and already started school. I know I need Bio and Chemistry but I'm unsure if I need physics or not. I have the option to switch out of it now so I need to know if I need it or not.
My sister has been telling me that I do and they start off of Physics 11 so I would need to take that course, but I just am not sure.
What exactly do I need and what's the career path for an Eye Surgeon? From what I understand I have to go to med school which would be more heavy on chemistry and biology I would assume.
I just don't want to switch into physics if I don't need to because it will mess up my other courses that I have lots of friends in.
Responses are really appreciated, thanks!5 AnswersHigher Education (University +)11 months ago

Numbness over 16 hours after smoking weed. Is there anything I can do to get rid of it, how long does it last?
I smoked for the second time yesterday night and didn't feel anything until I used a vape with nicotine where it all hit me. Ever since then I've had a fuzzy/numb feeling in my fingers and other parts of my body and it's been really disorienting.
I thought the effects would have been gone by now, my first time the fuzzyness/numbness went away about 4 or so hours after I had first smoked. Why is it taking so much longer?
I was wondering if there was anything I could eat or do to get rid of this feeling, I absolutely hate it and I don't want it to last a long time.

Nintendo Switch games are extremely pricey and I don't have too much money to buy the games I want. I remember a while back there were cartridges like "260 games in 1" that would give you a bunch of games essentially for free. Is there any way to do this for the Switch, or do I have to hack it.
If hacking the switch is the only option, what are the drawbacks. I've hacked a 3ds and gotten freeshop with no drawbacks or consequences that I've seen, is it a similar process?

A couple of days ago I visited the Queen Mary in California. I don't believe in ghosts, and still dismiss the encounter I had but I still wonder about it.
I went to the engine room, and was walking when I suddenly felt disoriented, lightheaded, or almost out of it. I look to my left and see a little girl and suddenly snap out of it.
I didn't think much about it at the time, and just dismissed it as my brain playing tricks on me, but I was wondering if this sort of "lightheadedness" was common when seeing a ghost.

I've noticed only recently that I've been quite forgetful. Here are some of the things I've noticed:
-When asking about something with a teacher, once they leave my desk I often forget bits of what they said and have to ask once more.
-I umpire baseball, and I commonly forget if I clicked the counter for each pitch which gets me really confused and unsure of the count.
-Sometimes people will tell me of things that are happening within minutes and I forget about it when it actually happens
-Once again in baseball, I'll see a play happen but then immediately be unsure because I somewhat forget what just happened.
I'm 15 years old, is this normal/okay? Could vaping w/ nicotine be the culprit? Thanks.3 AnswersMental Health1 year ago
I ve been doing textbook work and more than once this issue has showed up, and it s been stumping me for years if I m being honest. If we re rounding it to the nearest whole number, the 5 at the end changes the 9 to a 0 which bumps up the 4 to a 5, thus allowing us to round the 4.495 to 5. Is this a correct method? Or do I just look at one digit. Thanks.13 AnswersMathematics1 year ago
What happened at 40s? (I'm aware this picture is a velocity-time graph but if it was a position-time graph, what happened at 40s?). I said "the object moved forward in a constant motion to the position 0m from the position 40m [S] and got half points, so I'm wondering if I missed something (I have an exam tomorrow so I can't ask).
